Wave Properties and Interactions

Mr. Anderson discusses the concept of waves, explaining their importance in daily life. He differentiates between transverse and longitudinal waves, and describes key properties such as speed, frequency, and wavelength. The video also covers wave interactions like interference and behaviors such as reflection, refraction, and diffraction. A practical example of a tsunami is used to illustrate wave speed calculation.

What is a wave primarily defined as?

• A stationary energy form

• A static object in space

• A disturbance that moves through space and time

• A solid object that vibrates

Which type of wave moves perpendicular to the direction of motion?

• Longitudinal wave

• Transverse wave

• Radio wave

• Sound wave

In a longitudinal wave, how do the particles oscillate?

• In the direction of the motion

• Randomly

• In a circular motion

• Perpendicular to the motion

What is the formula for wave speed?

• V = Lambda / F

• V = F / Lambda

• V = F + Lambda

• V = F * Lambda

What does the term 'frequency' refer to in wave properties?

• The height of the wave

• The speed of the wave

• How often waves occur

• The length of the wave

What happens to the wavelength if the frequency of a wave increases?

• The wavelength increases

• The wavelength doubles

• The wavelength decreases

• The wavelength remains the same

What is the term for waves bending around a small opening?

• Reflection

• Refraction

• Diffraction

• Absorption

Which type of wave interaction involves a wave bouncing back from a surface?

• Reflection

• Refraction

• Diffraction

• Absorption

Why do low-frequency sounds bend more easily around obstacles?

• They travel faster

• They are louder

• They have higher energy

• They have longer wavelengths

How fast can a tsunami wave travel with a wavelength of 210 km and a frequency of 0.067 Hz?

• 140 m/s

• 67 m/s

• 310 m/s

• 210 m/s
